Do not forget to bring your water bottle!A responsible traveler will always travel with their re-useable/re-recyclable bottle. I personally use a stainless steel Arklite Waterbottle. It doesnt breakdown or in pieces! If needed, I could boil a cup of soup or sterilize thinks with the hot water.I do not recommend cheap plastic bottles, although they are hard to get away from these days. Single use plastics are a big no no in this day and age so refrain from cheap plastic.There are several options for water bottle with built in filter, I personally have not used them yet. I can imagine, like the lifestraw, they get clogged up after a weeks use. Unless it is the UV filter . Still though, i am not sure how well they work.
